Homo sapiens

Also known as HLASA; LEURS; PRLTS4; mtLeuRS

Gene ID: 23395 | Gene type: protein coding

About LARS2

Cytogenetic location: 3p21.31 Genomic coordinates (GRCh38): 3:45,388,576-45,549,407 (from NCBI)

This gene has 12 transcripts (splice variants), 206 orthologues, 7 paralogues and is associated with 5 phenotypes. Ubiquitous expression in kidney (RPKM 6.2), brain (RPKM 5.0) and 25 other tissues.

Summary

This gene encodes a class 1 Aminoacyl-tRNA Synthetase, mitochondrial leucyl-tRNA synthetase. Each of the twenty aminoacyl-tRNA synthetases catalyzes the aminoacylation of a specific tRNA or tRNA isoaccepting family with the cognate amino acid. [provided by RefSeq, Jul 2008]
